What size oscillating fan for a 1.2m x 1.2m grow tent?

Does anyone have any recommendations on what size of an oscillating fan I should use in a 1.2m x 1.2m tent? I currently have a 16" pedestal fan in there but I think its overkill for that size. I only have it because I had it my 2.4m tent which it was perfect for but it seems a bit big for this smaller tent and I could do with the floor space tbh it's getting a bit crowded in there at the moment.

I just can't fit one in. Most people are using 6" fans, as that's the smallest. Clip fans. Many of which can be mounted to the tent poles. Some oscillate but in such a tent you can set up a vortex. Some fixed fans can get the air going round like a twister. Then a central fan underneath can push up through the slower core, and up to the extraction.

I don't go bigger than 6" for canopy. I like to micromanage. A 6" can move the air over a few meters. A few working together can set up low and high pressure areas to increase the individual efficiencies. So you can see your air come in, go round, and leave. That's the goal. To get air in, around, and out. Oscillating fans are usually a game of 'hit and hope' and need a lot of space to be assigned zones. I can't remember the last one I saw with variable sweep arc. Leaving the choices on the market unsuitable for any targeted use.

At 1.2 we see a lot of people using 'case fans' as found in computers. A little electronics knowledge is needed, but these 12v DC electronically commutated (ec) fans can shift some air and make little noise. While the desk and stand fan sleeve bearings tend to last a year at most, PC fans last years. Using oil wicks and bust seals. I have some that are Mag-Lev so I don't see the bearings failing for some time. Such a fan is very low profile. I have some hanging from my LED panels. Following the canopy height. Something stand fans just ain't good for. Though I have hung them from a structure. They don't have to stand.

In general most fans/ ventilators I´ve had came with different settings ie stronger/ weaker blows. what´s your´s like`?

On the other forums I was on they were called ` muffin fans ´ :)hehe
